## Test we resolve symbolic relocations in .debug_* sections to a tombstone
|
|
## value if the referenced section symbol is folded into another section by ICF.
|
|
## Otherwise, we would leave entries in multiple CUs claiming ownership of the
|
|
## same range of code, which can confuse consumers.
